Choose Slack when your company relies on hundreds of SaaS webhook integrations across Windows, Linux, Android, and browsers. Request early access to Wonek when your founding team, agency, legal/research group, or engineering crew on Apple devices wants client-side MLS E2EE by default, low-latency direct P2P calls and screen shares, chunk-resumable P2P file transfers, offline-capable CRDT docs, and an integrated 5-view calendar.
| Capability | Wonek (Pre-Release) | Slack |
|---|---|---|
| Client-Side End-to-End Encryption | Yes — default MLS (RFC 9420) for all chats, calls & docs | No E2EE (even Enterprise EKM still decrypts in Slack cloud RAM) |
| Rich Technical Messaging | Rich text, inline code, math formulas, edits, pins & timers | Markdown/code blocks, threads, pins (no native LaTeX math) |
| Voice, Video & Screen Sharing | Direct P2P E2EE calls + screen share across iPhone, iPad & Mac | Cloud SFU Huddles (not end-to-end encrypted) |
| Collaborative Documents | Offline-capable Yjs/Yrs CRDT docs synced E2EE | Slack Canvas stored in cloud plaintext |
| Built-in Team Calendar | Native 5-view Shared Calendar (Day, Multi-Day, Month, Year, List) | Requires external Google/Outlook Calendar connector |
| Large File Sharing | Direct P2P transfer with chunk-level resumption | Cloud bucket uploads counted against workspace storage quota |
Why Enterprise Key Management (EKM) Is Not End-to-End Encryption
Even on Slack's highest enterprise tiers, Slack's servers must decrypt your messages in memory to index search, generate previews, and run server-side features—meaning a cloud breach, subpoena, or misconfigured export exposes plaintext history.
Wonek encrypts messages, calls, CRDT documents, and files on your Apple device before a single byte hits the wire. Neither Wonek relays nor offline message queues ever see plaintext.
Huddles That Travel Directly Peer-to-Peer
Instead of routing a quick screen-share code review between two engineers in the same city through a distant cloud SFU, Wonek's QUIC + port-prediction NAT traversal connects peers directly whenever possible for snappier cursor response and sharper text.
| Technical Dimension | Wonek | Slack |
|---|---|---|
| Cryptographic Key Custody | Keys stay strictly on user devices (Rust MLS + Noise QR) | Slack cloud holds keys or decrypts payloads for indexing/AI |
| Network Transport | QUIC / WebTransport (TLS 1.3) + port-predicted CGNAT P2P | HTTPS / TCP WebSockets + cloud WebRTC SFUs |
| Desktop & Watch Experience | Native macOS, iOS, iPadOS + Apple Watch calling/PTT | Electron desktop app; no Apple Watch calling/PTT |
| Personal + Work Separation | Dedicated Personal & Work contexts in one app | Separate workspace sign-ins; work-only focus |
| Offline Document Editing | Conflict-free Yjs/Yrs CRDT local edits merge on reconnect | Limited offline Canvas support |
Docs and Shared Calendars Without Leaving the Encrypted Boundary
With Yjs/Yrs CRDT collaborative documents and five built-in calendar views right beside Work profile conversations, teams stop leaking confidential roadmaps into external cloud tabs.
| Team Profile | Recommended Platform | Why |
|---|---|---|
| 500-person cross-OS enterprise using 80 SaaS bots | Slack | Deep third-party SaaS app directory and Windows/Android/Web parity |
| Security, executive, R&D, legal, or founder rooms on Apple gear | Wonek | True client-side MLS E2EE keeps IP, code, and M&A talk off cloud servers |
| Field + desk teams needing Apple Watch Push-to-Talk | Wonek | Instant E2EE wrist & mobile PTT alongside rich desktop chat |
| Sharing multi-gigabyte builds, datasets, or video renders | Wonek | Direct P2P chunk-resumable transfers consume zero cloud workspace quota |
| Teams wanting chat + docs + calendar without 3 cloud subscriptions | Wonek | All three live natively inside one E2EE workspace |
Frequently Asked Questions
Does Slack offer true end-to-end encryption for channels or Huddles?
No. Slack encrypts data in transit and at rest on its servers, where Slack infrastructure can decrypt it. Wonek enforces client-side MLS (RFC 9420) end-to-end encryption across all chats, calls, screen shares, and docs.
Can teammates edit Wonek documents offline on a flight?
Yes. Wonek's collaborative documents use Yjs/Yrs CRDTs so offline edits merge cleanly without conflicts once back online.
How can our Apple-based team test Wonek?
Wonek is in pre-release preparation for Mac, iPhone, iPad, and Apple Watch. Email support@wonek.com to inquire about team early access.
